A New 3-D Animated Map Of Our Cosmic Hometown
For the first time, we now have a three-dimensional map of our closest cosmic neighbourhood which shows not only how our nearest neighbour stars are distributed today - it also shows precisely how fast each of them moves, and in which direction. Astronomers have measured the velocities of many thousands of stars and computed both where they were... view more... (2004-04-06)
Gamma-ray bursts: are we safe?
For a few seconds every day, Earth is bombarded by gamma rays created by cataclysmic explosions in distant galaxies. Such explosions, similar to supernovae, are known as 'gamma-ray bursts' or GRBs. Astronomers using ESA's X-ray observatory, XMM-Newton, are trying to understand the cause of these extraordinary explosions from the X-rays given out... view more... (2003-09-17)
Old Galaxies in the Young Universe
Very Large Telescope Unravels New Population of Very Old Massive Galaxies [1] Current theories of the formation of galaxies are based on the hierarchical merging of smaller entities into larger and larger structures, starting from about the size of a stellar globular cluster and ending with clusters of galaxies. According to this scenario, it is... view more... (2004-07-06)
High-performance computing may improve combustion efficiency
Rising oil prices have revved momentum to develop more efficient combustion systems. But instrumental to this goal is a need to achieve greater understanding of the complex chemical reactions involved in combustion processes. view more (2005-08-30)
ESA finds a black-hole flywheel in the Milky Way
Far away among the stars, in the Ara constellation of the southern sky, a small black hole is whirling space around it. If you tried to stay still in its vicinity, you couldn`t. You`d be dragged around at high speed as if you were riding on a giant flywheel. In reality, gas falling into the black hole is whirled in that way. It radiates energy,... view more... (2002-04-26)
Oldest stars may shed light on dark matter, researchers report in Science
The universe's earliest stars may hold clues to the nature of dark matter, the mysterious stuff that makes up most of the universe's matter but doesn't interact with light, cosmologists report. view more (2007-09-14)
Violent galaxy seen in 3-D
Astronomers at the Gemini telescope in Hawaii have obtained a complete, multi-dimensional picture, of the dynamic flow of gas and stars at the core of an active galaxy [NGC 1068] located 70 million light years away. The image was achieved in a single snapshot and is the first time such a picture has been obtained by one of the new generation of... view more... (2002-03-21)
Herschel Space Telescope's SPIRE instrument package makes first-light observations
A scientific instrument package developed in part by the University of Colorado at Boulder for the $2.2 billion orbiting Herschel Space Observatory that was launched in May by the European Space Agency has made its first successful observations, targeting two star-forming galaxies near the Milky Way. view more (2009-07-13)
Discovery of Giant X-ray Loop Hints at Cosmic Particle Accelerator
Astronomers have found a vast loop-like structure, 20 light years across, adjacent to the most massive star-forming region known in our galaxy. The loop, which was observed in X-ray wavelengths, is 15 times the size of the Arches Cluster, a star-forming region close to the centre of the Milky Way. This is the first time that such a distinctive and... view more... (2005-03-31)
Rapid determination of urinary stone formation risk
Scientists at Bonn University, in co-operation with the firms NTTF and Theisen, have developed a novel appliance for rapid and accurate determination of the actual crystal formation risk in a patient. They are presenting their compact and ergonomic analyser in exhibition hall 3, stall C92 (Forschungsland NRW) at the international medical trade... view more... (2003-11-14)
Swift XMM-Newton Satellites Tune Into a Middleweight Black Hole
While astronomers have studied lightweight and heavyweight black holes for decades, the evidence for black holes with intermediate masses has been much harder to come by. view more (2009-11-11)
High Energy Mystery lurks at the Galactic Centre
A mystery lurking at the centre of our own Milky Way galaxy - an object radiating high-energy gamma rays - has been detected by an international team of astronomers. Their research, published today (September 22nd) in the Journal Astronomy and Astrophysics, was carried out using the High Energy Stereoscopic System (H.E.S.S.), an array of four... view more...

Scientists 'Weigh' Tiny Galaxy Halfway Across Universe
A tiny galaxy, nearly halfway across the universe, the smallest in size and mass known to exist at that distance, has been identified by an international team of scientists led by two from the University of California, Santa Barbara. view more (2007-10-04)
New deep space images of distant strip of sky to be available on Google
A global project to map a distant strip of the universe is releasing its data today to scientists and the public to be used as part of Google Sky, a new feature of Google Earth. view more (2007-10-04)
A new method to weigh giant black holes
How do you weigh the biggest black holes in the universe? One answer now comes from a new and independent technique that UC Irvine scientists and other astronomers have developed using data from NASA's Chandra X-ray Observatory. view more (2008-07-17)
Most Distant Group of Galaxies Known in the Universe
New VLT Discovery Pushes Back the Beginnings Using the ESO Very Large Telescope (VLT), a team of astronomers from The Netherlands, Germany and the USA [1] have discovered the most distant group of galaxies ever seen, about 13.5 billion light-years away. It has taken the light now recorded by the VLT about nine-tenths of the age of the Universe to... view more... (2002-04-09)
Heavy Stars Thrive among Heavy Elements
VLT Observes Wolf-Rayet Stars in Virgo Cluster Galaxies [1] Do very massive stars form in metal-rich regions of the Universe and in the nuclei of galaxies ? Or does "heavy element poisoning" stop stellar growth at an early stage, before young stars reach the "heavyweight class"? What may at the first glance appear as a question for specialists... view more... (2002-08-23)
Peering deep into space
People have always wondered where we, our Earth, our galaxy, come from. A group of scientist has now driven that quest one step further and taken a peak at how the stars that gave rise to most of the material found on our universe formed over cosmic history. view more (2009-05-28)
IBEX discovers that galactic magnetic fields may control the boundaries of our solar system
The first all-sky maps developed by NASA's Interstellar Boundary Explorer (IBEX) spacecraft, the initial mission to examine the global interactions occurring at the edge of the solar system, suggest that the galactic magnetic fields had a far greater impact on Earth's history than previously conceived, and the future of our planet and others may... view more...

Physicists uncover new solution for cosmic collisions
It turns out that our math teachers were right: being able to solve problems without a calculator does come in handy in the "real" world. view more (2008-01-11)
